USCGC Westwind (WAGB-281) was a Wind-class icebreaker that served in the United States Coast Guard as USCGC Westwind (WAG-281), the Soviet Navy as the Severni Polius, and again in the U.S. Coast Guard as USCGC Westwind (WAGB-281).
Westwind was one of the icebreakers designed by Lieutenant commander Edward Thiele and Gibbs & Cox of New York, who modeled them after plans for European icebreakers he obtained before the start of World War II. She was the fourth of seven completed ships of the Wind-class of icebreakers operated by the United States Coast Guard. Her keel was laid on 24 March 1942 at Western Pipe and Steel Company shipyards in San Pedro. She was launched on 31 March 1943 and commissioned on 18 September 1944.
Her hull was of unprecedented strength and structural integrity, with a relatively short length in proportion to the great power developed, a cut away forefoot, rounded bottom, and fore, aft and side heeling tanks. Diesel electric machinery was chosen for its controlability and resistance to damage.
Westwind, along with the other Wind-class icebreakers, was heavily armed for an icebreaker due to her design being crafted during World War II. Her main battery consisted of two twin-mount 5 in (130 mm) deck guns. Her anti-aircraft weaponry consisted of three quad-mounted Bofors 40 mm anti-aircraft autocannons. and six Oerlikon 20 mm autocannons. She also carried six K-gun depth charge projectors and a Hedgehog as anti-submarine weapons. After her return from Soviet service she received a single 5”38 cal. mount forward and a helicopter deck aft. Sometime after 1966 she had the forward mount removed.
